' 4 Claims. (01. 285-1) My invention relates to fastening apparatus and has particular relation to apparatus incorporating a tube which is to be securely mounted in a frame and to the ends of which torques are to be applied. I V

The present application constitutes an improvement of application for. Electro-chemical apparatus, Serial No. 173,603, filed November 9, 1 937, to George A. Hazen, and assigned, by mesne assignments, to the C. K. Manufacturing Company.

The above-mentioned application is directed to a cleaning system for colloidal suspensions, in which the cleaning takes place in a tube mechanically coupled to a coil system through which the colloidal liquid flows. The tube is mounted in a container and a potential is supplied to the liquid in the container through a terminal projecting laterally from the tube. I have found, in mounting the tube in the container in a manner taught by the prior art of which I am aware, that'when the tube is coupled to the supply coil and is subj'ected to a torque applied in tightening the coupling, it turns about its axis to a considerable extent. By the turning the lateral terminal is displaced and the electrical connection is broken or otherwise deleteriously affected.

It is; accordingly, an object of my invention to provide a mounting arrangement for a tubular element that shall prevent its turning about its axis when it is subjected to torques.

Another object of my invention is to provide a simple and inexpensive mounting for a tubular element which, when used, shall prevent the turning of the tubular element about its axis when torques of substantial magnitude are applied anywhere to the tubular element.

More specifically stated, it is an object of my invention to provide a contrivance for mounting a tubular element in a container in such manner that when the tubular element is subjected to torques, its position as regards its longitudinal axis shall not change.

According to my invention, I provide a collar which is secured to the tubular element by welding, soldering or sweating. The external sides of the collar are of such geometric structure that they engage the walls of the container when the tubular element is in position. Torques applied to the tubular element are counteracted by the engagement of the collar with a wall of the container and the tubular element is thus prevented from turning.

The novel features that I consider characteristic of my invention are set forth with particularity in the appended claims. The invention itself, however, both as to its organization and its method of operation, together with additional objects and advantages thereof, will best be understood from the following description of a '5 specific embodiment when read in connection with the accompanying drawing, in which Figure l is a View in top plan showing a preferred embodiment of my-invention;

Fig. 2 is an enlarged view in section taken along line 11-11 of Fig. Land Fig. 3 is an enlarged view in section taken along line IIIIII of Fig. 2.

-The specific structure and the detailed functioning of the-complete system involved in" the 15 present application will be found in the aboveinentioned Hazen application, and except for the specific features involved in the present invention, will be discussed only lightly here. For a more detailed discussion, reference is made to the said Hazen application.

The apparatus comprises, in general, oneor more tubular elements 5, each of which is coupled at its ends tothe coil I through which the colloidal liquid subjected to the treatment passes; Specifically, the Hazen invention applies to the treatment of malt liquids, such as beer, and in this case, the tubular element 5 is attached to the beer coil 1 extending from the beer barrel (not shown) to the spigot (not shown) at the dispensing bar. The tubes 5 are mounted in a suitable rectangular container 9 and extend through openings II in the side walls l3 of the container. The coupling to the coil 1 takes place outside of the container 9 and adjacent to the side walls I3.

The coupling devices l5 used are described in detail in the above-mentioned Hazen application. Each device includes a hexagonal tightening nut I! which is screwed on to the threaded ends I9 0 and 2! of the tubular element 5 fastening the terminals of the coil 1 to the tubular element in such manner that no leakage of the malt liquid takes place.

Within the tube 5, a metallic strand (not shown here) for applying a potential to the liquid is provided, as described in the Hazen application. The strand is connected to one output tap 23 of a supply transformer 25 through an insulated terminal 21 projecting laterally from the tubular element 5. The other output tap 29 of the transformer is grounded to the container wall l3 and thus a difference of potential is impressed on the liquid flowing through the tube 5.

In the apparatus constructed in accordance 5 with the teaching of the prior art,the tubular element'5 turnedlon its longitudinal axis when the nuts II'at the ends were tightened and carried with it the projecting terminal 21 breaking the connection between'the terminal and the transformer 25. In accordance with my invention, the turning isprevented by securing near one end 2| of the tubular element 5,'a collar 3| having a threaded circular hole 32 and external sides 33 and35 forming'a rectangle.v The threads I at the other end 19 of the tube 5 extend for a substantial distance and the tube 5- is slipped into "or the rear wall3l' of the container'fladjacent to the tubular element 5 and another side .35, which extends along the top of thecontaine'r ,9, engages a cover 39 which is, in the practice of my invention, secured to the container. nuts I! at the end of the tubular element 5 are now tightened, the. sides 33 and 35 of the collar press against the wall 31 and the c0ver'39 of the container and prevent the tubular element from turning on its axis. 1

Of course to withstand the torque applied, the collar 3| should be rigidly secured to the tube 5. Where the torque will always be relatively small, the collar 31 may be fastened simply by welding or'soldering. However, in general, the torque applied" may be large, and it is, therefore, desirable that the collar 3| be sealed to the tube 5 by sweating. The'sweating process used in the practice'of my invention comprises first engagingthe threads inrthe hole 32 of the collar 3l with those in the endZl of the tube. A suitable'acid flux is'then applied to the junction of the collar 3f and the tube 5, and then the tube 5 is heated by a blow torch in the region of the collar and solder is applied to the junction. The solderflows into the junction region between the threads of the collar to the tube 5.

Although I have shown and described a certain specific embodiment of my invention, I am fully aware that many modificationsthereof are pos- The collar 3lis of such dimen- When the 2,120,077 a 1 V i sible. My invention, therefore, is not to be restricted except insofar as is necessitated by the I claim as my invention:' 1.
